0.5A 0230.500ERT2SP 230 Series 2AG Axial Fuse Littelfuse Slo-Blo

Littelfuse 0230.500ERT2SP provides 0.5 A time-delay protection in the axial-leaded 2AG format. At this rating, nominal melting I²t is 1.64 A²s; breaking capacity is documented as 35 A @ 250 VAC; 10 kA @ 125 VAC/VDC; 80 A @ 310 VAC. The 0.25–1.25 A range is also documented for short-duration surge withstand in telecom equipment. The suffix corresponds to reel-and-tape packaging, 2,500 pieces, T2=63 mm with S option, helping distinguish this SKU from electrically equivalent 230 Series variants.
